JVM (Java Virtual Machine) is an abstract machine. It is called virtual machine because it doesn’t physically exist. It is a specification that provides runtime environment in which java byte code can be executed. It can also run those programs which are written in other languages and compiled to Java byte code.
JVMs are available for many hardware and software platforms. JVM, JRE and JDK are platform dependent because configurations of each OS are different from each other. But, Java is platform independent. There are three notions
of the JVM: specification, implementation, and instance.
The JVM performs following main tasks:
- Loads code
- Verifies code
- Executes code
- Provides runtime environment
